Hi,

    I'm trying to understand some of the information in an AWR report.

    Specifically,

  • The "executions" column and "Elap per exec" , in several cases is empty, but shows "DB time", "Elapsed TIme", and "CPU time". Can anyone explain that ?
  • 1 transactions shows 5.509,111 executions but no "elap per exec".

    These numbers are from 9 hours of snapshots.

Solaris 10, RDBMS, and RAC 10.2.0.4.

    Your comments are appreciated.

        thanks

  a.. Resources reported for PL/SQL code includes the resources used by all SQL statements called by the code.   b.. % Total DB Time is the Elapsed Time of the SQL statement divided into the Total Database Time multiplied by 100
